作者： Abbas A.Essa XU Qin jun XU Ke xi ZHOU Shi ping BAO Jia shan (College of Sciences, Shanghai University) College of Sciences Shanghai University

Meanders of thin films of TlBa 2Ca 2CuO 2 have been used to make radiation bolometers. Using cw HeNe at 632 nm the peak responsivity of these films is measured to be 0.560 V/W at the temperature of 106.0 K. The present experimental data agree well with bolometric response of irradiated films, and the calculations are presented to support this conclusion.

The patterning technologies and process order of high Tc(86K) super-conducting film bolometers have been studied. After the deposition, a conventional lithographic process was used to pattern the films with aqueous solution of HCl, and then the films were transferred into a tube furnace for annealing to form superconducting film. It eliminates the degradation of patterning process. The bolometric responsivity of approximately 34. 32 V/W is measured, and the detectivity is greater than 1. 62× 108cm · Hz1/2 · W-1, the noise equivalent powers NEP is 2. 1×10-9W.

It has been established that in plates made of hot-pressed ferroelectric ceramics PZT-19(Tc=300℃),after metal electrodes from Ag are burned into opposite surfaces with different depths of mechanical damage,counter-directional stationary deformation gradients and,accordingly,internal electric displacement fields create a stationary flexoelectric *** a result,unpolarized ceramics below the Curie temperature become a pyroelectric,and above it become a pyroelectric *** polishing the less damaged surface and replacing the Ag(valency v=3)electrode with Cr(v=6)by thermal evaporation in vacuum from the intact surface,a new thermally stable polarization is created,directed from the damaged surface in the interelectrode *** plates have an asymmetric dielectric hysteresis loop,retain the values of the pyroelectric effect and piezoelectric effect in the ferroelectric phase,as well as the bolometric effect in the paraelectric phase after repeated heating cycles to 400℃ and cooling to T_(norm).
